PLATE-SETTING AND HEEL-BLANK-BINDING DEVICE. 7

Application filed May 23, 1911.

To all whom it may concern:

Be it known that I, EDWARD T. BENTON, J12, a citizen of the United States, residing at lVashington, in the District of Columbia, have invented certain new and useful improvements in Plate-Setting and Heel- Blank-Binding Devices, of which the following is a specification.

My invention relates to shoe machines, and more particularly to devices for plate setting and heel-blank binding.

One object of my invention is to provide a device of this character, which will place a plate in an exact predetermined position. on a shoe heel.

Another object is to provide means for securing the plate to the heel and simultaneously therewith binding the heel blanks or lifts together; and doing both by a single operation of the machine.

Other objects will appear in the subjoined description.

The invention consists in certain novel parts and combinations hereinafter described and claimed.

An important feature of my invention is the combination with a heel-holding'machine, of a novel plunger casing provided with means for engaging and holding a plate in exact and predetermined position relatively to the position of the heel, to which heel said plate is to be secured.

Referring to the drawingsFigure 1 is a perspective view of an assembling machine provided with my improvement; Fig. 2 is a perspective of the plunger casing with a heel plate thereon; Fig. 8 is a perspective showing the adjusting plate in operative relation to the plunger casing and the back rest of the assembling machine; Fig. i is a top plan view of the plunger casing; Fig. 5 is a vertical section of Fig. 4, on the line .5-5; Fig. 6 is a vertical section of Fig. 4,

on the line 66; Fig. 7 is a top plan view of the plunger casing with a heel plate 10 in operative position thereon; Fig. 8 is a plan view of a portion of a punctured heel, with the heel plate 10 as it appears after having been secured thereto; Fig. 9vis a planview of a portion of a heel provided with a recess for the reception of the plate 10; and Fig.

.10 is a vertical section showing the plunger casing inoperative position relatively'to the parts immediately cooperating therewith.

suitably provided with drainways for the glue, and with adjustable means for engagmg and holding piles of blanks ready to be formed into shoe heels of different shapes and sizes; said means comprising the groups of adjustable plates 2, the clamps therefor 23, and the back-rest 4: arranged to move back and forth in the guides 5 to engage the straight or breast side of the heel blanks.

In front of the back rest 4 is located my improved plunger casing 6, which is provided at its upper end with an annular flange forming the head 6 Extending lon-' gitudinally through this casing from top to bottom are the two parallel. bores 7, each equidistant from the center of the casing. Projecting upwardly from the head 6 of the casing are the guide pins 8 arranged diametrically opposite each other on a line at right angles to a line passing through the longitudinal bores 7. The head 6 of the plunger casing is also provided with the large upwardly projecting pin 9, having its center slightly to one side of the center of the casing, and in alinement with the guide pins 8. This large pin 9 also acts as a guide P The special arrangement of guide pins here shown is simply to adapt the plunger casing to cooperate with the plates 10, which is one form of plate which I desire to secure to the heels of shoes. This particular plate forms part of the subject matter of my Patent, No. 995,656, dated June .20, 1911, and its uses are fully set forth therein. It need only be here said that this plate is to be snugly received into a recess 11 in the bottom of the heel, as illustrated in Fig. 9 of the drawings, and that this recess is located in a certain definite position in the bottom of the heel, so that when the plate 10 is received thereinto, said plate will always be entirely within the space inclosed by the series of punctures 12 (see Fig. 8) to be later made by the puncturing machine. so that no part of the plate will get into the path of the punches which form said punctures. Of course, if a different form of plate,or one used for a different purpose from this one, were to be attached to the heels of shoes, then the means employed for engaging the plate and holding it in the desired position on the heel, would be correspondingly changed, and this would involve no departure from the spirit of my invention, which itis deemed will be sufficientlyillustrated by showing it in a form perfectly adapted to apply this one form of heel plate.

The plunger casing 6 is snugly received through the base plate 1 into the upper end of the hollow cylinder 13, which is suitably secured to said base plate and projects downwardly therefrom as illustrated in Fig. 10.

For use with the plate 10, it is necessary that the guide pins 8 of the plunger casing 6 shall be in a line atright angles to the face of the adjustable back-rest a; and in order to adjust said casing quickly to this exact position, I employ the adjusting plate 14 illustrated in Fig. 3, which plate has at its forward end a straight edge 14* adapted to abut against the face of the back rest 4, and is further provided with the openings 15, adapted to receive the pins 8, and the opening 16 adapted to receive the large pin 9, of the plunger casing. These three openings, it will be observed, are arranged in a line at right angles to the front edge let of the adjusting plate, so that when this plate is placed on the plunger casing and is then brought into perfect abutting engagement with the rest 4:, said casing will be accurately brought to the exact position desired. And to enable the operator to more quickly and readily determine when the plate 1.4 and the rest 4 are in the proper relative position to each other for making the exact adjustment of the casing 6 just described. I provide the plate 14: with the line 14 adapted to be brought into engagement with the line 4) of the back rest.

It will be noticed that the plate lO to be secured to the shoe heel is providedwith the small openings 10 and the large opening 10 all three of which openings are in alinement, the small openings being adapted to receive the pins 8, and the large opening the pin 9 of the plunger casing, to hold the plate in the desired position on the head of said casing. The plate 10 is also provided with the two openings 16, on a line at right angles to a line passing through the openings 10 and 10 and adapted to register.

with the openings 7 of the plunger casing.

The plungers 17 move up and down in the bores 7 of the plunger casing 6 and extend downwardly into the opening 18 of the tubular cylinder 13, and are supported upon and operated by the power piston 19.

The nails 20 to be forced through the pile of heel blanks to bind the same together, and simultaneously therewith to secure the plate 10 in position on the heel, are sup ported heads downward in the bores 7 of the plunger casing upon the upper ends of the plungers 17. p

In operation, I first place the nails 20 in the bores 7 of the plunger casing, and then place one of the plates 10 up-onthe head of the plunger casing in the assembling machine, in the position illustrated in Fig. 2. I then take a number of blanks sufficient to form a heel of the thickness desired, placing them one upon the top of the other, selecting for my first blank one provided with an opening or recess 11, as illustrated in Fig.

mechanism of the assembling machine is also'so arranged for each diiferent size of heel to be formed, that when this recessed or apertured blank is placed in the machine, it will exactly. fit over the plate 10 ready to receive the same when the pile of assembled blanks is firmly pressed together by the machine. and held firmly together in the usual manner, an upwardmovement is imparted by any suitable mechanism to the power piston 19, which through the plungers 17 forces the nails 20 up through the openings 16 of the plate 10 into the pile of heel blanks, thereby setting and fastening the plate and binding the heel blanks together, all by a single operation, leaving the plate secured to the heel as shown in Fig. 8.

Attention is called to the fact that the openings 16 of the plate 10, are smaller than the bores 7 of the plunger casing, so that said openings form guides, as it were, to

While the blanks are thus pressed cause the nails to penetrate, vertically through the shoe heel, instead of being'deflected more or less from the ertical, as would frequently be the case withoutsome such guiding means for the nails. When the plate is used simply or chiefly as a guide for the nails it may be made quite thin.

Having thus described the principles in volved in my invention, and shown one form in which the same may be practically embodied, what I claim as new and desire to secure by Letters Patent is 1. The combination with an assembling machine provided with means for holding a plurality of heel blanks one above another in a predetermined position for forming a shoe heel, of means for holding a plate underneath the pile of blanks, to be attached to the bottom of the heel, also in predetermined position relatively to the heel to be formed.

2. The combination with an assembling machine provided with means for holding a plurality of heel blanks one abov e another in a predetermined position for forming a shoe heel, of a plunger casing provided with means for holding a plate underneath the pile of blanks, to be attached to the bottom of the heel, also in predetermined position relatively to the heelto be formed.

plurality of heel blanks one aLove another in a predetermined position for forming a shoe heel, of a plunger casing located underneath the pile of blanks and provided with projections adapted to engage corresponding apertures in a plate to be attached to the under side of the heel to be formed, said projections being arranged to hold said plate in predetermined position relatively to the heel to be formed.

4. The combination with an assembling machine provided with means for holding a plurality of heel blanks in predetermined position for forming a shoe heel, of a plunger casing provided with projections adapted to engage corresponding apertures in a plate to be attached in predetermined position to the heel to be formed, said projections being on a line extending centrally from the front side to the rear side of the shoe heel.

5. The combination with an assembling machine provided with means for holding a plurality of heel blanks in predetermined position for forming a shoe heel, of a plunger casing provided with projections adapted to engage corresponding apertures in a plate to be attached, in predetermined position, to the heel to be formed, said projections being on a line extending centrally from the front side to the rear side of the heel, said plunger casing being also provided with longitudinal bores for nail-driving plungers, said bores being on a line at right angles to the line passing through said projections.

- 6. In assembling machines for uniting heel blanks into heels, a plunger casing provided at its upper end with projections on a line forming the diameter of the casing, and having parallel longitudinal plunger bores with their centers on a line at right angles to the line of said projections, and equidistant from said line, one on one side thereof and the other on the other side.

7. In assembling machines for uniting heel blanks into heels, a plunger casing provided at its upper end with projections on a line forming the diameter of the casing, two of said projections being of equal size and equidistant from the center of the casing, and the remaining projection being larger in diameter than the other two, and having its center to one side of the center of the casing, said casing having parallel longitudinal bores equidistant from its center on a line extending at right angles to the line of said projections, and on the side of the center of the casing opposite the side on which the large projection is located.

8. In an assembling machine for uniting heel blanks into heels, a plunger casing provided with longitudinal bores to receive the nails for binding the heel blanks together, a guide plate for the nails, and means for holding said plate on the casing, said plate having apertures adapted to register with the bores of the casing but of smaller diameter.

9. The combination with a machine adapted to hold a shoe heel in a predetermined position, of a plunger casing provided with bores adapted to receive nails to be forced into said heel, a guide plate for directing the nails as they are thrust into the heel, and means for holding said plate on the casing, said plate having apertures adapted to register with the bores of the casing, but of smaller diameter.

10. In assembling machines for uniting heel blanks into heels, and having an adjus: table back rest for engaging the straight side of the heel blanks, and a plunger casing located in front of said back rest, and provided with projections adapted to engage corresponding openings in a plate to be attached in a given position to a shoe heel; an adjusting plate for said plunger casing, said plate having apertures adapted to be engaged by the projections on the plunger casing and a straight edge adapted to engage tlieback rest when the plunger casing is brought to the proper position.

In testimony whereof I have aflixed my signature in presence of two witnesses.
